Thanks Albert for version 4.5 of Rubi.
fyi;
I tried it on the 3rd Charlwood which in previous Version Rubi did not integrate,
http://12000.org/my_notes/ten_hard_integrals/inse3.htm#x430003
and was hoping it will now, so it can get 10/10, but still difficulties show:
ShowSteps = False; Int[ArcSin[Sqrt[x + 1]  Sqrt[x]], x]
Out[68]= (x)*ArcSin[Sqrt[x]  Sqrt[1 + x]] + Subst[Int[Sqrt[1  x^2 + x*Sqrt[1 + x^2]], x], x, Sqrt[1 + x]]/Sqrt[2]
ps. is it possible to make the default to be ShowSteps=False instead of True? Most of the time one does not want to see the steps, at least at first. Just as a suggestion.
Thanks, Nasser
